Database Indexes

Implementations

impl DatabaseIndexes

pub fn new() -> Self

New empty database indexes

pub async fn bulk_index<'a, E>(&self, events: BTreeSet<E>) -> HashSet<EventId>

where E: Into<EventOrTempEvent<'a>>,

Bulk index

pub async fn bulk_import(&self, events: BTreeSet<Event>) -> BTreeSet<Event>

Bulk import

Take a set of Event, index them and return only the ones that must be stored into the database

pub async fn index_event(&self, event: &Event) -> EventIndexResult

Index Event

This method assume that Event was already verified

pub async fn query<I>(&self, filters: I, order: Order) -> Vec<EventId>

where I: IntoIterator<Item = Filter>,

Query

pub async fn count<I>(&self, filters: I) -> usize

where I: IntoIterator<Item = Filter>,

Count events

pub async fn negentropy_items( &self, filter: Filter ) -> Vec<(EventId, Timestamp)>

Get negentropy items

pub async fn has_event_id_been_deleted(&self, event_id: &EventId) -> bool

Check if an event with EventId has been deleted

pub async fn has_coordinate_been_deleted( &self, coordinate: &Coordinate, timestamp: Timestamp ) -> bool

Check if event with Coordinate has been deleted before Timestamp

pub async fn delete(&self, filter: Filter) -> Option<HashSet<EventId>>

Delete all events that match Filter

If return None, means that all events must be deleted from DB

pub async fn clear(&self)

Clear indexes
